Microwave-assisted solvent-free synthesis of 3- (4-substituted piperazin-1-yl)alkyl imidazo 2,1-b 1,3 benzothiazol-2(3H)-ones as serotonin(3) (5-HT3) receptor antagonists
A series of novel 3-(4-substituted piperazin-1-yl)alkylimidazo2,1-b1,3benzothiazol-2(3H)-ones were prepared by microwave irradiation using alumina as solid support and also by a conventional method. The compounds were characterized by spectral data and the purity was ascertained by microanalysis. Th...
